I like the way it shows my monthly income, spending per month, and how much of my advertising budget is left. It's very easy to use once you have some experience with Google AdWords. There are no real downsides that I can think of. I guess it's possible to get confused if you aren't used to using this type of software. If you're looking for something simple but useful, then this is a great tool! I'm managing our PPC advertising campaign, as well as tracking our performance data. This software helps me pull all of my information together into one place so I can make quick decisions about where we should spend more or less money.
